Of course, you need to trust me. But I have the number written down on paper in front of me.

Good Luck!

Updated: Only one try per person (please don't use multiple email addresses, I run these contest all the time) and I will announce the winner as soon as I get 3 correct answers. But you need to be the first three, if I get four correct answers, the 4th does not win.

***CONTEST IS OVER***
The answer was 5. If I have time, I'll post a summary of the attempts.
